pg更新JSON字段
jsonb_set()
示例:
- user表的info字段为
jsonb
类型 info内city键更新为
Beijing
update \"user\" set \"info\" = jsonb_set(info, \'{city}\', \'\"Beijing\"\') where name = \'wang\';
若jsonb可能为空(null)
update \"user\"
set \"info\" = jsonb_set(coalesce(\"info\", \'{}\'), \'{city}\', \'\"Beijing\"\')
where name = \'wang\';
